What You Need to Know
Mango flesh provides fermentable sugars that heterofermentative lactic acid bacteria convert to lactic, acetic, and carbonic acids, lowering the pH to 3.5–4.0. The 10–15 % NaCl brine creates an osmotic barrier that suppresses spoilage microbes while allowing halotolerant LAB to dominate. Phenolic compounds from mustard, fenugreek, cumin, coriander and chili add antimicrobial activity and contribute to the characteristic aroma.
